Foreword  
 
Development of the East African Standards has been necessitated by the need for harmonizing 
requirements governing quality of products and services in East Africa. It is envisaged that through 
harmonized standardization, trade barriers which are encountered when goods and services are 
exchanged within the Community will be removed.  
 
In order to achieve this objective, the Partner States in the Community through their National 
Bureaux of Standards, have established an East African Standards Committ ee. 
 
The Committee is composed of representatives of the National Standards Bodies in Partner States, 
together with the representatives from the private sectors and consumer organizations. Draft East 
African Standards are circulated to stakeholders through  the National Standards Bodies in the 
Partner States. The comments received are discussed and incorporated before finalization of 
standards, in accordance with the procedures of the Community.  
 
East African Standards are subject to review, to keep pace with technological advances. Users of 
the East African Standards are therefore expected to ensure that they always have the latest 
versions of the standards they are implementing.

4 Hydraulic road binder  
 
A hydraulic road binder, whe n mixed with water hardens both in air and under water and remains 
solid, even under water.  
 
A hydraulic road binder is a factory produced hydraulic binder, supplied ready for use, having 
properties specifically suitable for road and rail bases and sub –bases, capping layers, soil 
stabilisation and soil improvement.  
 
A hydraulic road binder shall consist of a powder made from a blend of different constituents and 
statistically homogeneous in composition. A high degree of uniformity in all hydraulic road binder 
properties shall be obtained through continuous mass production process.  
 
NOTE Continuous production refers to the process, the definition of the product, its composition and properties but does not 
imply a 24 hour production.  
 
Qualified and skilled  personnel and the facilities to test, evaluate and adjust product quality are 
essential for producing hydraulic road binders included in this standard.  
 
The manufacturing process and its control shall ensure that the composition of hydraulic road 
binders is kept within the limits of this standard.  
 
5 Classification   
The standard strength of a hydraulic road binder is the compressive strength determined in 
accordance with EAS 148 -1 at 28 days.  
 
 
2 © EAC 20 19 — All rights reserved  DEAS 981:2019 
 
 
Four classes of strength are covered in this Standard: class 5, class 12,5, class 22,5 and class 32,5, 
the minimum standard strength being taken as the criterion of classification.   
NOTE The strength classes are incorporated to enable the ma nufacturer to control quality and are not related to performance in 
bound mixes.  
 
For strength classes 22.5 and 32.5 a subclass E is defined by a minimum content of Portland 
cement clinker of 20% and an additional requirements for strength at 7 days  
 
6 Constituents  
 
6.1 Main Constituents   
The main constituents of hydraulic road binder shall be selected from the following:   
Constituents which conform to EAS 18 -

specially selected, inorganic natural mineral materials, inorganic mineral materials derived from the 
clinker production process or constituents as specified in 6.1 unless they are indicated as main 
constituents in the hydraulic road binder.   
Minor additional constituents, after appropriate preparation and on the account of their particle size 
distribution, improve the physical properties of the hydraulic road binder (such as workabi lity or water 
retention). They can be inert or have slightly hydraulic, latent hydraulic or pozzolanic properties. 
However, no requirements are set for them in this respect.   
Minor additional constituents shall be correctly prepared, i.e. selected, homogen ized, dried and 
comminuted depending on their state of production or delivery. They shall not increase the water 
demand of the hydraulic road binder appreciably or impair the resistance of the bound mixture to 
deterioration in any way.  
 
6.3 Calcium sulphat e

9 Conformity criteria  
 
9.1 Introduction  
 
Compliance of hydraulic road binder with the  requirements of this Standard shall be continuously 
assessed on the basis of spot samples taken at the points of release after production according to 
EAS 148 -7, and tested according to EAS 148 Parts, 1,2,3,4 and 6 as relevant. This clause presents 
the ne cessary basic definitions, specifies the conformity criteria to be applied including the 
evaluation procedures and specifies the conformity requirements including the minimum sampling 
frequencies for each property to be tested.  
 
NOTE This standard does not  deal with acceptance inspection at delivery. It is recommended that any acceptance at delivery of 
HRB hydraulic road binder should be at least in accordance with the conformity criteria specified in 9.2.3.  
 
9.2 Conformity criteria and evaluation procedure  
 
9.2.1  General  
 
Conformity of hydraulic road binder with this standard is assumed if the conformity criteria specified 
in 9.2.2.and 9.2.3 are met.  
 
9.2.2  Statistical conformity criteria  
 
9.2.2.1 General  
 
Conformity on the basis of continuos sampling shall  be formulated in terms of a statistical criterion 
based on:  
 
The required mechanical and chemical properties defined as characteristic value, as specified in 
clause 7 of this standard   
The probability P k on which the definition of the characteristic value  is based, as specified in 
table 4.  
 
 
6 © EAC 20 19 — All rights reserved  DEAS 981:2019 
 
 
 
The allowable probability of acceptance CR of hydraulic road binder not conforming to the 
requirements, as specified in table 4.  
 
NOTE  Conformity evaluation by a procedure based on a finite number of measurements can only produce approximate   
value for the proportion of results outside the characteristic value in a population. The bigger the sample, the better the  
approximation. The selec ted probability of acceptance CR controls the degree of approximation by the sampling plan.

9.2.2.2 Inspection by variables  
 
The conformity shall be evaluated on the totality of autocontrol test results obtained on all samples 
taken during the control period. For this calculation the test results are assumed to be normally 
distributed.  
 
The conformity is verified when the follow ing equation(s) is (are) satisfied:  
 
x - kA s ≥ L and  
 
x + k A s ≤ U 
 
 
© EAC 20 19 — All rights reserved  7 DEAS 981:2019

U is the specified upper limit given in ta bles1 and 2 and 3 referred to in clause 6.   
The acceptability constant k A depends on the probability P k on which the definition of the 
characteristic value is based, and on the number n of the test results. Values of k A are listed in table 
5. The values of  kA listed in the table are valid for 5% probability of acceptance CR of hydraulic road 
binder not conforming to the requirements.  
 
9.2.2.3 Inspection by attributes   
The number of test results outside the characteristic value c D . out of a totality of autocontrol test 
results obtained on all samples taken during the control period shall be counted and compared with 
an estimated number c A, calculated from the number n of autocontrol test results and the probability 
Pk as specified  in table 4.  
 
Conformity is verified when the following equation is satisfied  
 
cD ≤ cA 
 
Values of c A, are listed The values are valid for 5 % probability of acceptance CR of hydraulic road
