J. of GEOMATE.In Indonesia, most of the rigid pavement generally use to carry heavy traffic. The combination of trapped infiltration water and repeated traffic loading will generate void between the base layer surface and surface layer base (erosion). Erosion phenomenon could lead to the loss of foundation support, short-term service life issue. Base layer with drainage type like pervious concrete could be useful to tackle those problems. KENSLABS program which is based on the finite element method has been widely used to analyze the pavement response. Some advanced parameters are varied in the simulation to analyze their impact against fatigue life through the mechanistic approach. It was found that the thickness ratio between the surface layer and the base layer can influence the rigid pavement fatigue life. The slab thickness should also be limited when pervious concrete is used as a base layer with an unbonded condition. Pervious concrete with the bonded interface has a longer fatigue life than lean concrete with the bonded interface. The difference among the advanced property values from base layer material and the thickness ratio between the surface layer and the base layer plays an important role in fatigue life value as well. Either in unbonded condition or in bonded condition, fixed base layer with a minimum thickness is more recommended when pervious concrete is used as a base layer because it requires thinner total slab thickness. In sum, pervious concrete could be recommended as an alternative base layer to replace lean concrete.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Base layer,Fatigue life,KENSLABS,Pervious concrete,Rigid pavement[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors appreciate the financial support from the Bandung Institute of Technology research program.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.21660/2019.63.04607[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
