Abstract
A large number of domestic and international literatures have studied the pavement performance of composite modification of Buton rock asphalt and different asphalt modifiers. It is found that basalt blending can greatly improve the performance in an all-round way, in which high-temperature stability and low-temperature cracking resistance have superimposed effect. Waste rubber powder blending has little overall performance improvement. With diatomite blending the performance can exceed SBS modified asphalt. The research on composite modification of Buton rock asphalt still needs further study.
Highlights
With the rapid development of the national economy, all walks of life are booming, which brings the growing demand for the transportation industry
As one of the important pavement forms of high-grade highway, asphalt pavement has some unavoidable defects, such as cracks, ruts, pits, looseness, etc., which will cause the actual service life of some asphalt pavement to fail to reach the design service life specified in the specification 1 2 3
It becomes more and more urgent and important to delay the appearance of early damage phenomenon and improve the service performance of pavement and prolong the service life of pavement, and the best way to solve the problem is to start from the fundamental raw materials
Summary
With the rapid development of the national economy, all walks of life are booming, which brings the growing demand for the transportation industry. It becomes more and more urgent and important to delay the appearance of early damage phenomenon and improve the service performance of pavement and prolong the service life of pavement, and the best way to solve the problem is to start from the fundamental raw materials. The high temperature stability of BRA mixture is better, and the temperature sensitivity is reduced, which can greatly improve the antirutting performance of asphalt concrete pavement [2] Buton rock modified asphalt is stable because of its good compatibility with base asphalt, so its preparation process is simple and its storage is convenient. In order to solve the current situation, many scholars have gradually changed their research direction from the single modification of BRA to the composite modification of BRA and other modifiers
