BRIEFING: STUDY OF THE RELATIONSHIP BETWEEN STIFFNESS PARAMETERS FOR BASE MATERIALS
(ICE Publishing, 2015-05-25)The stiffness of the base layer is an important parameter for designing the pavement thickness needed to support traffic loads. It is normally related to the California bearing ratio (CBR). The spectral analysis of surface ... -
COMPARATIVE STUDY ON USING STATIC AND DYNAMIC FINITE ELEMENT MODELS TO DEVELOP FWD MEASUREMENT ON FLEXIBLE PAVEMENT STRUCTURES
(ELSEVIER, 2018-07-10)The deflection basin obtained through backcalculation analysis is compared with the measured deflection basin to determine the moduli of each pavement layer. Most computer programs use multi-layered elastic theory (MET) ... -

DETERMINATION OF DEFLECTION BASIN USING PAVEMENT MODELLING COMPUTER PROGRAMS AND FINITE ELEMENT METHOD
(2020-06-22)Several methods can be used to model pavement structures, namely multilayered elastic theory (MET), finite element method (FEM), or finite difference method (FDM). In this study, three computer programs, KENLAYER and ... -
Determining The Effects of RH-WMA on the Engineering Properties of Bitumen
(2019-02-18)This study aims to investigate the engineering properties (i.e., physical, chemical, and adhesion properties) of bitumen incorporated with RH-Warm Mix Asphalt (RH- WMA) additive. Base bitumen with a penetration ... -
The Development of Local Community Institutions for Community-Based Forest Management
(LP3M UMY, 2011-01-01)The problems of exploitation on forest management in Indonesia are complex. There are lots of reasons that lead to forest exploitation. First of all, economic reasons such as increasing gross national product which leads ... -
EFFECT OF INPUT SOURCE ENERGY AND MEASUREMENT OF FLEXIBLE PAVEMENT DEFLECTION USING THE SASW METHOD
(International Journal of Pavement Engineering, 2019-10-17)This paper presents the effect of input source energy on the results of spectral analysis of surface wave (SASW) evaluation of flexible pavements in terms of maximum and minimum wavelength. A series of surface wave tests, ... -

The effects of polymer modified asphalt binder incorporating with chemical warm mix additive towards water quality degradation
(2020-08-15)Naturally, asphalt binder has compacting and mixing temperatures higher than 150 C. Both temperatures can be increased by modifying the pristine penetration grade asphalt binder with polymer. However, the warm-mix asphalt ... -
EFFECTS OF REDISET ON THE ADHESION, STRIPPING, THERMAL AND SURFACE MORPHOLOGIES OF PG76 BINDER
(ELSEVIER, 2019-11-17)Apart from lowering the production and application temperature, Warm Mix Asphalt (WMA) additive has the potential to enhance the adhesion property of the base binders. Surface free energy (SFE) from contact angles was ... -
ENGINEERING CHARACTERISTICS OF NANOSILICA/ POLYMER-MODIFIED BITUMEN AND PREDICTING THEIR RHEOLOGICAL PROPERTIES USING MULTILAYER PERCEPTRON NEURAL NETWORK MODEL
(ELSEVIER, 2018-08-21)This study examines the effect of mixing varying percentages of nano-silica (NS), i.e. 2, 4 and 6% (by weight of polymer-modified bitumen, PMB) with PMB, in unaged and aged conditions. The Fourier transform infrared ... -
