Long-Term Skid Resistance Evaluation of GAC-16 Based on Accelerated Pavement Testing

Table 2

Test results of the coarse aggregate technical indicators.

Test index	Test method	Technical requirements	Test results
			Diabase 1	Diabase 2
Crushed stone value (%)	T0316	≤20	9.4	13.0
Los Angeles wear loss (%)	T0317	≤24	10.6	14.3
Polished stone value (BPN)	T0321	≥42	46	44

Note. Crushed stone value can characterize the ability of stone to resist crushing, and it is expressed as a percentage of the mass of stone smaller than the specified particle size after crushing test. The polished stone value can reflect the ability of coarse aggregate to resist the tire polishing.
