Title: Asphalt paving material for cold laying
Inventor: KITAGAWA KOJI
IPC: C08L95/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an asphalt paving material which is one containing a product obtained by crushing waste asphalt concrete, nevertheless having not deteriorated quality, being advantageous in environmental protection, developing sufficient strengths just after laying, and being capable of being stored for a long term. SOLUTION: This material is obtained by mixing a product obtained by crushing waste asphalt concrete with a novel aggregate and hot asphalt and is further mixed with an asphalt-compatible difficultly volatile oil which causes the hot asphalt adhering to the surfaces of the aggregate particles to swell to such an extent that the hot asphalt deforms and bonds the aggregate particles to each other only when the hot asphalt is strongly pressed at prdinary temperature. Because the asphalt is kept in a swollen state even at ordinary temperature, it can not be solidified at ordinary temperature and can remain unchanged. When it is strongly pressed at ordinary temperature, it forms a tough mass. This material emits no oil vapor because of the difficult volatility of the oil used.
