Pavement Distresses

A road pavement is a structure composed of structural elements, whose function is to protect the natural subgrade and to carry the traffic safely and economically. When the roads are open to traffic, the pavements deteriorate with time due to the combined influence of the traffic, construction material and the environment. Due to the great complexity of the road deterioration process, performance models are the best approximate predictors of expected conditions. Hence, the aim of this research work is to develop a predictive model for the rate of potholes deterioration for a section of the Ijokodo –Apete road in Ido Local Government Area of Ibadan. In actualizing the above aim, a reconnaissance survey and inventory were conducted on the selected road section and potholes were discovered as the predominant pavement distresses, chainages were established for easy identification of the potholes positions, some selected potholes were measured and their volume change was monitored. The pavement structural evaluation and traffic volume data were collected. Regression models were developed for the potholes deterioration rate using SPSS (Statistical package for social sciences) package. Conclusively, the model with the highest coefficient of determinant (R2 ) and least standard error was selected as the reliable model and was used to determine the deterioration rate of the independent variables(traffic volume and structural number) selected at random.

Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A

Standard Quality

Asphalt pavement is permanently influenced by various environmental conditions and traffic load. Because of this after a certain period numerous defects may appear on the surface of the road pavement. These defects include peeling, chipping, pots, cracks etc. The low water proof resistance of the asphalt concrete (conditioned by low adhesion of the bitumen to aggregate surface) is considered to be one of the reasons for appearance of these defects. Adhesion promoters’ use is the most common method to increase adhesion activity of pavement bitumen. Goal. The objective of the current research work is the evaluation of influence of the domestic adhesion promoter iDOP on the conventional and adhesion properties of bitumen. Methodology. To achieve this goal, the following was done: the effect of the adhesive promoter iDOP on the standard quality indicators of bitumen was determined according the requirements of the current standards DSTY 4044 and SOU 45.2-00018112-067; the effect of the adhesive promoter on the adhesion of bitumen to the glass surface (according to the DSTU B.V.2.7-81 method) and to the surface of aggregates with different mineralogy was evaluated by the rotating bottle method according to DSTU EN 12697-11; the thermal stability of the iDOP-PH promoter was tested by simulating the technological ageing of bitumen according to the method given in GOST 18180 and the RTFOT method. Results. Grounding on the experimental data obtained, it was found that the adhesive promoter iDOP-PH does not affect the standard indicators of the quality of bitumen (penetration, softening and breaking point temperatures, ductility). During hardening with the RTFOT method, a slight inhibitory effect of the promoter is observed, which appears as an increase in the values of residual penetration and ductility compared to bitumen without promoter. The iDOP-PH promoter increases the adhesive capacity of bitumen, which is confirmed by the adhesion data determined by the improved method given in GOST B.V.2.7-81 and the rolling bottle method. Originality. It is shown that the iDOP-PH promoter has a relevantly low thermal stability. With this the main factor affecting the decrease in thermal stability is the long time exposing of the binder at high temperature by GOST B.V.2.7-81 method. Practical value. It is shown that the promoter concentrations recommended by the supplier are insufficient, and to ensure the required values of the adhesion (standardized in СОУ 45.2-00018112-067) it is advisable to increase the concentration of the iDOP-PH promoter in bitumen to 0.3 - 0.6%.

Due to the importance of road transport an adequate identification of the various road network levels is necessary for an efficient and sustainable management of the road infrastructure. Additionally, traffic values are key data for any pavement management system. In this work traffic volume data of 2019 in the Basque Autonomous Community (Spain) were analyzed and modeled. Having a multidimensional sample, the average annual daily traffic (AADT) was considered as the main variable of interest, which is used in many areas of the road network management. First, an exploratory analysis was performed, from which descriptive statistical information was obtained continuing with the clustering by various variables in order to standardize its behavior by translation. In a second stage, the variable of interest was estimated in the entire road network of the studied country using linear-based radial basis functions (RBFs). The estimated model was compared with the sample statistically, evaluating the estimation using cross-validation and highest-traffic sectors are defined. From the analysis, it was observed that the clustering analysis is useful for identifying the real importance of each road segment, as a function of the real traffic volume and not based on other criteria. It was also observed that interpolation methods based on linear-type radial basis functions (RBF) can be used as a preliminary method to estimate the AADT.
