The selection of styrene butadiene rubber as the main modifier to develop styrene butadiene rubber modified asphalt felt is because styrene butadiene rubber has the following advantages and characteristics:1. Good comprehensive performance: Styrene-butadiene rubber is a general rubber with good comp
Bitumenpolymer modified bitumenis a kind of road material which improves the performance of bitumenby adding polymer. As a commonly used material in road construction, bitumenhas certain elasticity and adhesion, but it is easy to soften at high temperature, easy to become bri
The composite modified bitumen(SBS/CRMA) was prepared by adding the styrene butadiene-styrene block copolymer (SBS), which was pre-swelled by furfural extraction oil, with the addition of rubber powder.The effects of furfural extraction oil content, rubber powder content, stirring temperature
In the highway maintenance, how to make use of emulsified asphalt equipment to improve the properties of the modified asphalt and performance. Modified emulsified asphalt as a new kind of highway asphalt pavement maintenance material, people's attention. The types of asphalt modifie
Before operation, check whether the construction requirements, surrounding safety facilities, asphalt storage capacity, operation parts of asphalt stripping equipment, instruments, asphalt pumps and other working devices are normal. They can be used normally only if there is no fault.
