Description : In 1980 a construction project was constructed with two different bituminous mixes that incorporated 53% and 63% crushed aggregates. The project was designed using the 50-Blow Marshall method. The pavement was unstable because it rutted during the 11 years that it was monitored. Cracking was low when compared to the original roadway. Rut depths varied in which the pavement with the 63% crushed aggregate rutted 16% less than the pavement with the 53% crushed aggregate. The additional 10% crushed aggregate (63% vs. 53%) resulted is a 3.8% increase in cost. The report also includes a laboratory study of 'Crushed vs. Uncrushed Aggregates in Bituminous Mixes'. The report concluded that increasing the crushed aggregate above 50% will result in increased mix stiffness.
