Analisis Persentase Gradasi Agregat AC - WC Dalam Campuran Beraspal dengan Metode Rothluchs

The development of technology and information very rapidly, spurring
growth and increasing mobility of the population, resulting in an increase in the
number of vehicles crossing the highway. The road is a staple in people's daily
activities to facilitate, accelerate and support all efforts for the welfare of society,
such as the state of the city of Padang at the moment. Padang city prone to
earthquakes and tsunamis, so in need of increased transportation facilities and
infrastructure ie roads as one of the evacuation routes such as roads Alay - By
Pass.

During the implementation of industry practices in the field of Capacity
Building Project Alay Street - By Pass (evacuation routes) the city of Padang, the
authors found many interesting findings, one of the interesting findings of the
author pick up as a case study at the end of the project entitled Analysis of
Percentage of Aggregate Gradation AC-WC Mixed Methods in Paved with
Rothluchs.

Discussion of using tables and calculation of the percentage of sieve
analysis of aggregate mixture using a method Rothluch charts. From the analysis
using a graphical method Rothluch type A and type B does not meet
specifications, so to get a percentage of the aggregate mixture used method of trial
and error. Assumed screen and filler to the stone dust from 3% - 12% and taking
the average value of each assumption and compare with the average middle
specification. Obtained assuming 7% of the screen and the filler into the stone
dust with an average value of 53.02, while the average value of 53.06 was the
specification. Obtained a mixture of aggregate percentage of screen 9%, medium
41%, stone dust 40% and filler 10%
