Title: Pavement-mixture with superior mixing and compacting property and method of pavement construction
Inventor: YOSHINAKA TAMOTSU
IPC: E01C7/22
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To ensure quality and durability even in the case of relieving temperature conditions by preparing a pavement-mixture composing binder to generate and hold small bubble particles in the binder at heat-mixing and compacting the mixture. SOLUTION: Aggregate particles forming a pavement mixture are covered with a bubble particle-containing binder. When compacting external forces are added thereto, bubble particles existing in the aggregate covering binder serve as a bearing so as to make aggregate particles easily slidable and also make aggregates readily move to bite one another, and further the binder is flow-filled therein so that gaps between the aggregate become small, thereby achieving a closely compacted state for pavement. Existence of bubble particles in a binder to be composed from the manufacturing period to the execution period yields an excellent thermosensitivity, aggregate covering property, and compacting property, as a result, relaxation can be accomplished in weather conditions such as temperature or executing conditions.  Accordingly, emission of carbon dioxide gas can be controlled or manufacturing fuel cost can also be reduced at heating materials, so that it is effective in environmental problems.
