Abstract

Abstrak Penelitian dilakukan pada papan semen sekam padi dengan variasi kadar semen 75%, 100%, 125%, 150%, 175% dan 200%. Analisis menunjukkan bahwa Papan semen sekam padi yang dilapisi dengan anyaman bambu nilai berat papan, kerapatan, kadar air, pengembangan tebal dan kuat lentur rata-rata lebih besar masing-masing sebesar 49,381%; 13,342%; 30,206%; 146,106% dan 74,642% dari papan semen tanpa anyaman bambu. Sedangkan nilai penyerapan air papan semen sekam padi yang dilapisi dengan anyaman bambu rata-rata lebih rendah 37,092%. Papan semen sekam padi tanpa anyaman bambu yang memiliki sifat fisik dan mekanik yang paling baik serta masih memenuhi standar SNI 03-6861.1.2002 adalah papan semen sekam padi dengan komposisi kadar semen diatas 125% PC. Sedangkan untuk papan semen sekam padi dengan anyaman bambu semuanya memenuhi standar, tetapi yang memiliki sifat fisik dan mekanik yang paling baik serta kuat lentur yang tinggi adalah papan semen sekam padi dengan komposisi kadar semen 1 limbah : 1,75 PC. Kata kunci : Sekam Padi, Anyaman bambu, Kuat lentur

Abstract

ABSTRACT Evaluation of the condition of the road pavement structure required prior to maintenance and repair . This study aims to determine the type of damage , extent of damage , and determine how to repair the damage road pavement cement - ngluwar . The research includes assessing pavement conditions visually using pci method by dividing the road into 52 segments , dynamic cone penetrometer test ( dcp ) subgrade , test california bearing ratio ( cbr ) field in base layer , traffic surveys , and analysis using the additional thick layer methods of aashto , 1993 . The results showed that , the visual type of damage that occurs is alligator cracking , block cracking , depression , long and transverse cracking , patching , raveling & weatering , rutting , extensive damage to 25.30 % , the dominant type alligator cracking damage 14.23 % of the total area and obtained an average value of 50.06 pci or pavement conditions are (fair ) . Dcp test results of subgrade cbr values obtained on average 10.33 % , the results of the field test cbr cbr base layer is obtained on average 65.70 % , the survey results obtained lhr traffic as much as 2397 vehicles / day . Repair damage in accordance with the location , type , and extent of the damage , it is better if done additional coating ( overlay ) , a thick layer of additional analysis , with a design life of 10 years acquired an additional layer 5cm thick . Keywords : pavement, condition, damage, subgrade, repairs
