Asphalt-Paving Publication: Comply with Asphalt Institute (AI) MS-22, "Construction of Hot Mix Asphalt Pavements," unless more stringent requirements are indicated. NTS: A Pre-Construction Meeting is beneficial for large projects with multiple mix designs and other requirements. Paragraph “e” can be deleted on smaller projects. Pre-construction Meeting: Conduct conference at Project Site. Review methods and procedures related to hot-mix asphalt paving including, but not limited to, the following: Review condition of subgrade and preparatory Work. Review requirements for protecting paving Work, including restriction of traffic during installation period and for remainder of construction period.

NTS: Typically temporary pavement repair is used during cold weather, when asphalt plants are not operational. Keep this as a work item if the Work is anticipated to be completed during the winter months. Edit the temporary pavement repair material below as required for project. TEMPORARY PAVEMENT REPAIR Temporary pavement repair shall be Cold Mixed Asphalt (CMA) Intermediate, No. 8 or 9 in accordance with INDOT Standard Specifications latest edition, Section 403. CHIP & SEAL MATERIALS Furnish No.9 and No.11 and No.53 stone as specified in the most recent edition of the Indiana Department of Transportation (INDOT) Standard Specifications. AE-90’s Modified Sealing Asphalt shall also be supplied. A. NTS: Edit Article “2.5”: Pavement Marking Materials below, to suit the needs of the project. Including desires of Owner and Authority Having Jurisdiction over the pavement. Regarding Handicap parking space marking verify local requirements. Delete paint colors not required for project. PAVEMENT MARKING MATERIALS Pavement marking materials shall be in accordance with INDOT Standard Specifications latest edition, Section 808 for Pavement Traffic Markings.
