This report explains the necessity of creep tests in the pavement design process for asphalt concrete pavement. The creep properties in asphalt concrete are the cause of rutting in existing pavement structures.from both static and dynamic creep tests were used to develop creep curves which are characteristic of the permanent deformation behavior of the asphalt mixes tested.This study investigates the rutting susceptibility of various asphalt mixtures subjected to static and dynamic creep tests. Four wearing course gradations were selected; and asphalt . Therefore, an attempt was made to assess moisture sensitivity and its interaction with permanent deformation through performing a dynamic creep test on coarse graded and .
Permanent deformation of asphalt mixes is caused as a result of several parameters, including; asphalt mix characteristics, climatic conditions, and traffic loading .
In this study, a dynamic creep test was performed on asphalt concrete samples reinforced with four different types of fiberglass grid as well as on unreinforced samples.The dynamic creep test was able to quantify the effect of aggregate type and gradation on rutting potentials of mixes. Mixes with crushed aggregates performed better in the creep test than the . Recent researches show that there is a serious need for more accurate methods to evaluate polymer modified asphalt mixtures. In this research, dynamic creep test was .
Dynamic creep test is a simple performance test used to measure the rutting resistance of the bituminous emulsion stabilized mixes. The test is reliable in predicting the permanent.
for examining the long-term permanent deformation and unmodified asphalt mixtures is the dynamic creep test (Kaloush and Witczak [27]). Additionally, the results of the wheel tracking test and the dynamic creep test have strong correlations (Fontes et al. [28]). Numerous studies using the uniaxial (unconfined) creep test have been carried Dynamic creep test was conducted on unmodified and BRA modified asphalt mixture using UTM25 machine. Asphalt cement of C170 was used as the base asphalt binder for unmodified asphalt mixture and BRA modified asphalt mixtures were made by substituting the base asphalt with 10, 20, and 30% (by weight of total asphalt binder) natural binder . A closer look at a number of researches carried out on the stripping potential of asphalt mixtures shows that there is no global agreement on a comprehensive procedure for evaluation of the moisture sensitivity of these mixtures. Therefore, an attempt was made to assess moisture sensitivity and its interaction with permanent deformation through performing a .Mehrara and Khodaii (2010) evaluated the moisture resistance of two asphalt mixtures (dense and coarse graded) using a dynamic creep test. The dynamic creep test was performed on both dry and .
The main objective of this research is to determine the effect of rubber on dynamic creep of asphalt concrete mixtures. Rubber was used as an additive to the asphalt concrete mixtures at five contents: (0, 5, 10, 15 and 20%) by volume of binder. Then, they were exposed to simulation of creep test through Universal Testing Machine (UTM).Investigating the Creep Properties of PET-Modified Asphalt Concrete Taherkhani, H.1*and Arshadi, M.R.2 1 Associate Professor, Civil Engineering Department, University of Zanjan, . Uniaxial dynamic creep test at 40°C was conducted on the cylindrical specimens of the mixtures. The load was applied in two different frequencies of 0.5 and 5Hz. The dynamic creep test was conducted to study the effect of PET on the resilient modulus, creep stiffness, and accumulated strain of the asphalt concrete samples. The test was carried out according to the British Institute Standard test BS EN 12697-25 (2016) [ 81 ] using the Universal Testing Machine (UTM) (Fig. 5 ). These include the static/dynamic creep test, wheel track test, and indirect tensile test. Monismith et al. (1975), quoted by Kalyoncuoglu and Tigdemir (2011), developed the dynamic creep test which is thought to be one the best methods to evaluate the resistance of asphalt concrete to permanent deformation.
The dynamic modulus test consists of testing samples at te mperatures of - 10, 10, and 35°C and at loading frequencies 0.1, 0.5, 1.0, 5, and 10 Hz at each temperature for the development of .

Abstract. Loading mode is an important but under-estimated factor for the dynamic modulus test of asphalt concrete. This article presents a comparative laboratory study of using uniaxial-compression, two-point bending and three-point bending to test dynamic modulus of 12.5 mm asphalt concrete (AC) with two asphalt materials. Dynamic moduli |E*| and phase . This impact is further investigated by evaluation of performance of asphalt concrete modified with gilsonite at elevated temperatures using repeated dynamic creep test. The results showed that .
A strategy that has significant positive effects on the environment and economy is the addition of waste materials to new roads and highways. The purpose of this study is to investigate how adding the Waste Iron Powder (WIP) affects concrete mixes and asphalt binder. WIP was used as an additive of asphalt cement and asphalt concrete mixtures with different . Thirty wearing course mixtures with variable combinations of constituent materials and gradations were tested at three temperature conditions (i.e. 25, 40 and 50 °C) and two stress conditions (i.e. 300 and 500 kPa) using uniaxial dynamic creep test (DCT). Consistent ranking has been observed at various test temperatures and stress conditions. In the respect, bitumen 60/70 penetration grade with 0.5% of Forta-Fi, 0.1% Kenaf fibre and 0.5% PET by weight of asphalt mixture were prepared. Dynamic Creep Test was performed in accordance .

This study investigates the rutting susceptibility of various asphalt mixtures subjected to static and dynamic creep tests. Four wearing course gradations were selected; and asphalt mixture’s specimens were fabricated using Superpave gyratory . It can be seen from Fig. 13 that the trend in accumulated strain in case of static and dynamic creep test for the modified and unmodified asphalt binder mixes are similar. As expected, the accumulated strain values were higher in case of static creep test when compared to dynamic creep test in both modified and unmodified asphalt binder mixes.
