Stone Matrix

In 1991, the Wisconsin Department of Transportation and the asphalt paving industry in the state decided to construct a trial installation of an asphalt paving technology that had piqued the interest of a group of professionals who had recently toured Europe. The success of that initial trial was the basis of the decision to conduct a thorough evaluation of stone matrix asphalt (SMA). Subsequently, six projects were constructed at various locations around the state. Each project contained six test sections utilizing various fiber and polymer-modified SMA mixes. Besides evaluating the various types of SMAs, this research effort also contained elements for evaluating the impact of aggregate size and aggregate hardness on the effectiveness of the SMA mixes. These projects were constructed over a period of 3 years; the last one was constructed in 1994. All the projects were evaluated from the standpoint of ease of construction and performance. Although the ease of construction was to be evaluated mostly on a subjective basis, the performance measures were established to be objective and measurable. The performance measures were amount of cracking, friction characteristics, overall pavement distress, amount of rutting, noise impacts, and ride. Although the data collected so far are limited because of the short time the pavements have been in place, they point to an asphalt pavement that resists cracking and rutting, while providing a good ride and excellent frictional qualities. The SMAs demonstrate promise of being a durable and long-lasting asphalt pavement.

Large data sets of Washington State Department of Transportation (WSDOT) pavement construction and condition data are linked together and used to investigate an implemented change in in-place density to lower specification limit (LSL) from 91% to 92%. This serves as a test case for using such large in-service data sets to create analysis value for a state DOT. Findings include: (1) WSDOT field density has remained relatively steady at 93% for over 20 years; (2) raising the density LSL to 92% will likely result in more contractor effort to achieve higher densities; (3) no clear trend links density with better pavement condition; (4) raising the density LSL will likely result in fewer problematically low densities; and (5) there is no evidence of differing pavement performance based on asphalt content, gradation, or nominal maximum aggregate size.

ABSTRACT Traffic is increasing day by day due to increased vehicle ownership and infrastructure development. As the modern highway transportation has high speed, high traffic density, heavy load and channelized traffic, bituminous concrete is subjected to various types of distress such as rutting, fatigue cracking and raveling. Fatigue cracking occurs because bituminous layers are weak in tension. Therefore reinforcement of the bituminous mixes is one approach to improve tensile strength. Natural fibers can be used for reinforcing as a substitute for synthetic fibers due to their lower cost, ecological recycling and low specific gravity. Among natural fibers growing attention is being paid to coir fiber due to its easy availability, good wearing resistance and more durable property. Also rutting along wheel path causes vehicle hydroplaning during rainy seasons due to loss of skid resistance. As well as water accumulated over the longitudinal depressions damages bond between binder and aggregates. Therefore there is a need for a durable mix which can increase the service life of pavement thus reduces life cycle cost. This study is about use of coir fiber in pavement construction to improve the performance characteristics of the asphalt mixture being used. Stone matrix asphalt mixture is a rut resistant and durable mix which is reinforced with coir fiber and tested for various performance characteristics. Coir fiber is a sustainable material which can be used for rutting resistant mixture.   Keywords: Stone matrix asphalt, Coir fiber, rutting

Tujuan peneIitian ini untuk menguji karakteristik Campuran Stone Matrix Asphalt (SMA) Kasar dengan memanfaatkan Sungai Sa’dan Kelurahan Pangli Kecamatan Sesean Kabupaten Toraja Utara dari hasil penelitian laboratorium.Metode yang digunakan untuk penelitian ini ialah membuat beberapa uji karakteristik yang berwujud material aggregat kasar, halus, filer serta aspal yang kemudiam membuat rancangan komposisi lalu benda uji dibuat dalam bentuk campuran beraspal panas Stone Matrix Asphalt (SMA) Kasar dan kemudian melakukan Marshall test untuk mendapatkan Stabilitas Marshal sisa (SMS) menggunakan K.A.O. Adapun penelitian ini dilaksanakan di laboratorium Jalan dan Aspal Fakultas Teknik Sipil Universitas Kristen Indonesia Paulus Makassar, yang memberikan hasil Karakteristik material perkerasan berupa Batu Sungai Sa’dan Kelurahan Pangli Kec.Sesean Kab. Toraja Utara telah memenuhi Spesifikasi standar Bina Marga 2018 yang dapat digunakan dalam campuran beraspal panas. Melalui uji Marshall didapatkan karakteristik Stone Matrix Asphalt (SMA) Kasar dengan kadar aspal 6,00, hingga 7,00% dengan kenaikan 0,25%. 7,00% adalah K.A.O yang digunakan pada Marshall Immersion campuran SMA dan diperoleh Stabilitas Marshal Sisa (SMS) sebesar 97,53% dimana nilai ini sesuai dengan Spesifikasi Umum Bina Marga 2018 yaitu minimal 90%.
