LABORATORY EVALUATION OF EXPOSED-AGGREGATE CONCRETE PAVEMENT

Exposed aggregate cement concrete pavement (EACCP) is a portland cement (PCCP) with aggregates protruding approximately 1.55 mm from the pavement surface mortar. Laboratory experiments indicate that EACCP has many advantages over traditional PCCP because of its special surface texture. These advantages include higher skid resistance, more gentle surface light reflection, and lower perceptible noise. This paper presents the results from a factorial study on sample preparation that included aggregate selection, curing time, brush wash, and maturity. The test results show that a good EACCP's surface friction coefficient is about 50% higher than the traditional PSSP's; its abrasive mass loss is less than 15% of PCCP's; its rolling noise is 9% lower than PCCP's; and its reflection coefficient is 50% less than PCCP's. These results provide guidelines for the field implementation of EACCP.
