Low-Temperature Tar Content of Bituminous Materials. Part 1. Dense Tar Surfacing with Crushed Rock Aggregate

摘要

The limited study using the two crushed rock aggregates with high- and low-density tars of coke-oven and low-temperature carbonization sources has shown that equal volumes of tar are required, regardless of carbonization source. It is recommended that, when the density of the tar is below 1.12 g/ml, an additional reduction in tar content of 0.3% by mass should be applied to the recommendations in the British Standard.
