This study evaluated the potential for improving the cracking resistance of microsurfacing mixtures using polymer and fiber additions. Three mixtures were evaluated in this study: a fiber reinforced mixture using 1/4″ glass fibers, a polymer (SBR) enhanced emulsion, and a mixture using a combination of polymer and fibers. The polymer enhanced samples and the combination samples showed improvements for the Texas Overlay Tester and the Semi-Circular Bend Test. The greatest improvements in performance for the Texas Overlay Tester were obtained from the polymer enhanced sample, whereas the greatest improvements in the Semi-Circular Bend Test were obtained from the combination samples.

该研究评估了使用聚合物和纤维添加剂提高微表面混合物抗裂性的潜力。本研究评估了三种混合物：使用 1/4" 玻璃纤维的纤维增强混合物、聚合物 (SBR) 增强乳液以及使用聚合物和纤维组合的混合物。聚合物增强样品和组合样品在 Texas Overlay Tester 和 Semi-Circular Bend Test 方面表现出改进。Texas Overlay Tester 性能的最大改进来自聚合物增强样品，而半圆形弯曲测试的最大改进来自组合样品。
