The aim of this study is to measure and quantify perceived intensity of discomfort due to vibration in a vehicle in situ considering complete vehicle dynamic behaviour. The shaker table based discomfort curves or the road test results may not accurately and universally indicate the true level of human discomfort in a vehicle. A new experimental method, using a seated human in a car on the four-post rig simulator, is proposed to quantify discomfort. The intensity of perception to vibration decreased with decreasing input and increasing frequency; the rate of change is different from the published literature; the difference is large for angular modes of inputs. Vehicle dynamic response is used to inform and analyse the results. The repeatability of the method and the fact that they are in situ measurements may eventually help reduce reliance on the road tests. Furthermore, discomfort curves obtained, subsequently, can be used in predictive models.

South Gobi road of 240-km flexible pavement was constructed from UKHAA KHUDAG to GASHUUN SUKHAIT in South Gobi, Mongolia in 2011. However, due to the heavy traffic and severe weather condition, early distresses have occurred from a length of 100-km flexible pavements in South Gobi road after one year service life. In order to enhance crack and rutting resistances and to improve paving quality control in South Gobi road, polymer modifier is selected to reduce rutting at high temperature and cracking at low temperature and warm-mix asphalt (WMA) additive is selected to reduce the mixing and compacting temperatures and provide better compaction on the road and the ability to haul paving mix for longer distances. This paper adopted comprehensive asphalt tests to evaluate physical and rheological characteristics, and crack potential at low temperature for use in a South Gobi road. Laboratory tests were performed on asphalt binder with a polymer modifier and warm-mix asphalt additive by conducting the following tests: softening test, ductility test, SuperpaveTMtest and cold bending test. These test results of asphalt binder with SBS polymer modifier and warm-mix asphalt additive were significantly more positive than those of typical asphalt binder. On the basis of test results, it can be concluded that the asphalt binder with SBS polymer modifier and WMA additive is stronger and less susceptible to rutting and crack than typical asphalt binder used in South Gobi.

In order to realize the goal of development between an area to another region through land transportation, it is very important in the construction of road facilities. In civil construction science, material that can be used as material greatly determines the quality and quantity of the construction.Base construction or foundation layer is very besides as a foundation layer also to bear the burden of vehicles or traffic that passes through the construction of the road, so that material is needed quality.For the implementation of planning for pavement thickness of pavement construction layers, it is necessary to consider all the factors that can affect road construction such as road function, age of plan, traffic, carrying capacity of land, regional factors, surface index (IP), equivalent numbers, average daily traffic, Pavement Thickness Index and Relative strength Coefficient.In making road construction, the material used determines the quality of the road, so in the implementation of road construction it is necessary to carry out laboratory testing, which in the labor test discussed is coarse aggregates originating from Solok Sumatra B arat district, which will later be used for Base Class A on the road. The implementation of the Tests that the authors carried out was the calculation of the aggregate class A class proportion, Aggregate Specific Gravity, Compaction Test of the Base Class A aggregate mixture, Laboratory CBR Testing, and CBR Plan determination.The test results obtained can be a recommendation whether or not the aggregate can be used. Laboratory test results were obtained from the results of the testing of aggregate Class A material derived from solok. Testing the aggregate proportion of base A meets the requirements because it enters the filter 2 "to filter 200, Testing the aggregate density obtained density 2,685, Testing for aggregate compaction obtained Weight Content = 2.763% and Optimum moisture content = 5.75%. From the value of the above test results it can be concluded that the coarse aggregates originating from Solok can be used for Base Class A on Road construction work.

The system design test results are obtained that when the sensor detects an object with a certain distance, the  sensor will issue a signal to the micro which is then forwarded to the charging driver circuit to turn on the relay. The relay functions as a switch or switch that will fill the liquid in the bottle, when the driver is charging on, the process of filling the liquid occurs in the bottle, and the micro filling process issues a signal in the active motor driver circuit. The conveyor driver is active after giving a signal from Arduino Uno, the conveyor will stop after the sensor detects a bottle then stops, and the micro sends a signal to turn the motor driver down on the bottle cap to close the bottle on. When the bottle closing process is complete the motor driver backs up actively moving the road conveyor back. The percentage error of theoretical value and measurement of the difference is small and when filling the liquid in a bottle takes 17 seconds until the bottle is fully filled and by using the micro, the liquid filler on the bottle and the bottle cover can be completed properly.

In order to comparatively study the effect of warm mix modifiers on the road performance of guss asphalt, the guss asphalt mixtures, whose asphalt aggregate ratio were 8.5%,9.0%,9.5% respectively, were mixed with 0%,1%,2%,3% of the RH and Sasobit warm mix modifiers. Then by means of Lueer test, penetration test, wheel track test and low-temperature bending test, the performance of guss asphalt were evaluated. The test results show that: RH and Sasobit can effectively improve the workability of guss asphalt; RH is better than Sasobit in reducing viscosity of guss asphalt; RH reduces the high-temperature properties of guss asphalt; On the contrary, Sasobit can improve the hightemperature performance of guss asphalt; RH and Sasobit have an adverse impact on the crack resistance of guss asphalt in low temperature, so their content should not too high. Guss asphalt has characteristics of high construction temperature and energy consumption. In order to reduce construction temperature, based on energy conservation, low-carbon emission environment, reduce the aging of asphalt principle, warm modifiers could be used to reduce the viscosity of guss asphalt at high temperatures[1-5]. Sasobit modifiers imported from Germany are used much more to improve the workability of guss asphalt. In this paper, 0%, 1%, 2%, 3% RH and Sasobit warm mix modifier were mixed with the aggregate ratio of 8.5%, 9.0%, and 9.5% of the Guss asphalt to compare and analyzed the performance of those two warm modifiers on Guss asphalt.
