Evaluation of Alabama Limestone Aggregates for Asphalt ...
In a recent study sponsored by AHD, limestone aggregates were evaluated in asphalt wearing courses (1). Laboratory tests showed that limestone aggregates were beneficial in in creasing the stability of the mix and its resistance to moisture damage. In two field evaluations, mixes with approximately
Evaluation of limestone crushed dust aggregates in hot mix ...
Sep 01, 2017 · The objective was to evaluate the inclusion of limestone aggregates in hot mix asphalt mixtures, through laboratory tests. The HMA mixtures were designed by Marshall and Superpave and submitted to indirect tensile-strength, resilient modulus, moisture damage and Flow Number.
Evaluation of limestone crushed dust aggregates in hot mix ...
Laboratory evaluation of HMA mixes with granite and limestone aggregates were investigated. Using limestone in fine fractions improved the mechanical behavior in HMA mixes. Limestone as filler in HMA mixes can improve permanent deformation resistance. The results confirmed the efficiency of limestone as fine fraction and filler in HMA mixes.
Evaluating Performance of Limestone Prone to Polishing
The study undertook the evaluation of the performance of different mortar fractions and aggregate concentrations to determine the effect of coarse aggregate usage in the top mortar layer on pavement friction performance, as well as the effect of the substitution of different aggregates in place of Vanport limestone…

Evaluation of Carbonate Aggregate Using X-Ray Analysis
Evaluation of Carbonate Aggregate Using X-Ray Analysis. WENDELL DuBBERKE AND VERNON J. MARKS. Iowa has more than 13,000 miles of portland cement concrete (PCC) pavement. Some pavements have performed well for over 50 years, while others have been removed or overlaid due to the premature deterioration of joints and cracks.
