“…The curing time is determined on the basis of the 10% limit ( 23 ). Later on, this test method has also been utilized (with modifications) by several researchers to investigate the effect of several other variables on performance characteristics of chip seals using the 10% limit ( 25 – 30 ). However, such limit was not necessarily applicable to the HWT device abrasion test.…”

Chip seal treatments are used by many state departments of transportation and counties to cover minor fatigue and low-temperature cracks, retard raveling by reducing the moisture infiltration, and improve friction. Long-term performance of a chip seal treatment is affected by several factors including the type and morphology of the aggregates, emulsion/binder type, and most importantly, the microstructural characteristics such as the percent embedment of aggregates. This paper documents the efforts towards establishing performance-based threshold values of the percent embedment to minimize the common chip seal distresses (i.e. aggregate loss and bleeding). The laboratory performance tests were performed to evaluate aggregate loss and bleeding using a retrofitted Hamburg wheel tracking device. Two emulsion types (CRS-2M and CSEA) and two aggregate sources (slag and natural aggregates) were included in the testing program. Digital image analysis techniques were utilized to quantify and analyze the laboratory test results with respect to the percent embedment as well as chip seal macrotexture. Based on the test results, the minimum and maximum percent embedment thresholds for chip seals are established as 58% and 70%, respectively.

“…This treatment is formed by spreading well-graded aggregate over an asphalt-binder membrane as a thin wearing course. The unique advantages of chip seal compared to other types of pavement surface treatment include its low initial cost and rapid construction [1,2]. However, issues such as aggregate loss, low-temperature cracking, and bleeding are still frequently observed with the increasing application of chip seal in China [3][4][5].…”

This study investigated the laboratory performance of basalt fiber (BF) used as an asphalt-chip seal. Specimens of the basalt fiber asphalt-chip seal (BFACS) at various contents of styrenebutadiene-rubber (SBR)-modified emulsified asphalt (EA) and BF were prepared. These were subjected to a series of tests, including plate impact, sweeping, pull-out, and direct shear tests, to inspect their bond performances. The results indicate that BF can significantly improve the performances of the aggregate retention and the interlayer bond of asphalt-chip seal. This study evaluated the performance of BFACS in terms of the low-temperature anti-cracking, interlayer bond, and skid resistance. Specimens with different EA and BF contents and lengths were fabricated to quantify their respective impacts. The findings suggest the optimal BFACS design at 1.8 kg/m 2 EA and 70 g/m 2 BF with a length of 70 mm. The BF fiber was proven to substantially enhance the performance of asphalt-chip seal compared to the controlled specimens (0 % BF). Specifically, the tensile strength, shear strength, and surface texture depth for the optimal design were increased by 29.2 %, 51.6 %, and 14.2 %, respectively.

“…Raveling performance of chip seal can be quantified using different methods. Two commonly used approaches include calculating the percentage of aggregate weight loss after testing ( 15 , 16 ), and measuring macrotexture loss. Macrotexture loss is considered to be the most relevant indicator for evaluating raveling in chip seal.…”

The characteristics of the load applied by traffic, namely, vehicle speed and load magnitude, play a critical role in the raveling performance of chip seal pavement, which is often overlooked in literature. Furthermore, a sustainable chip seal constructed out of tire derived aggregate (TDA) has been recently introduced. Unlike mineral aggregate, rubber is a time-dependent material, and its properties are greatly influenced by the magnitude and rate of loading. Introducing TDA in chip seal has increased the significance and need to investigate the effects of vehicle speed and load on chip seal. This study investigated the raveling performance of different chip seal specimens constructed out of mineral and TDA, as well as a hybrid tire derived–mineral aggregate, under various loading speeds and magnitudes using a small-wheel traffic simulation device. The findings revealed that both load and speed significantly affect the texture loss of conventional and TDA chip seals, but in opposite ways. Conventional chip seals experienced increased texture loss with higher load and speed, while TDA chip seals showed a decrease. The use of TDA as an aggregate in chip seal resulted in a 23% reduction in macrotexture loss under increased load and a 56% reduction in macrotexture loss under increased speed compared with conventional chip seal. This improved performance is attributed to the dynamic properties of TDA, such as internal hysteresis, time-dependent behavior, and load transmissibility.
