“…The infrared spectrum was recorded using the Perkin Elmer Fourier Transform lnfrared (FTIR) spectrometer by scanning in wavenumbers ranging from 4000 to 400 cm -1 . The FTIR method is explained elsewhere [19]. All FTIR plots were recorded as a transmitted radiation against the wave numbers.…”

In this research, asphalt composite was produced by combining asphalt and rice husk silica. The ratio of asphalt and silica were 1:1.5; 1:1.7; and 1:1.9 respectively and calcined at temperature of 150 oC. Functional group characteristics of asphalt composites were examined by FTIR and XRD. The FTIR and XRD studies revealed that the main Functional groups are Si-O-Si, C-H, and structure amorph of silica.

“…The bamboo mat, bamboo curtain, and closely arranged and spaced radial bamboo curtain were put into the cold plasma processor, and the bamboo material was modified by using a based concrete template during the cold plasma modification process (treatment gas O2, treatment power 160 W, and treatment time 90 s) optimized by the orthogonal test (Thompson 2006;Karahancer et al 2014;Sheng et al 2018). This is the result of previous experiments.…”

To reduce the density of bamboo-based concrete formwork on the premise of meeting the performance requirements, the bamboo was first treated by cold plasma, and then by increasing the distance between the adjacent bamboo strips of the radial bamboo curtain in the middle layer, the internal porosity was increased. The production of lightened bamboo based concrete formwork, which meets China’s forestry industry standards, was achieved. Four groups of bamboo-based concrete formworks with different slab structures were designed. The key results showed that slab structures have an extremely significant effect on the density, MOR, MOE, IB, and TS of the bamboo-based concrete formwork. A group of optimal slab structures was obtained by comparing their physical and mechanical properties (1st and 9th floor-phenolic resin impregnated paper, 2nd and 8th floor-bamboo mat, 3rd and 7th floor-tangential bamboo curtain, 4th and 6th floor-radial spaced bamboo curtain). Based on the required physical and mechanical properties, its density was 0.62 g·cm-3, which was 27.1% lower than that of traditional bamboo plywood template (0.85 g·cm-3) circulating on the current market. This lightened BBCF can save raw materials, facilitate transportation and reduce labor intensity in the application process so that it will be widely used in building construction.

“…Marshall Stabilitesi, bitümlü sıcak karışımla imal edilen yol kaplamasının trafik yüklerine bağlı oluşabilecek deformasyonlara karşı gösterdiği direnç ölçüsü olarak tanımlanmakla birlikte Türkiye'de Karayolları Teknik Şartnamesi'ne göre [1] farklı üstyapı tabakalarının stabilite bakımından sağlaması gereken belirli minimum değerler mevcuttur. Stabilite, bitümlü sıcak karışımların önemli bir özelliği olup geliştirilmesine yönelik birçok araştırma yapılmaktadır [2][3][4][5]. Marshall testi ile belirlenen akma ise bitümlü sıcak karışım ile imal edilen silindirik numuneye (briket) test esnasında uygulanan yükleme ile brikette kırılmanın meydana geldiği yükleme seviyesinde oluşan düşey deformasyonu ifade eder.…”

ÖzBu çalışmada, bitümlü sıcak karışım özelliklerinden olan ve Marshall Testi ile deneysel olarak belirlenebilen akma değerinin malzeme ve karışım özellikleri temelinde regresyon modelleri ile tahmin edilmesi amaçlanmıştır. Bu kapsamda Ankara Büyükşehir Belediyesi sınırları dahilindeki aşınma ve binder tabakalarının inşaatına yönelik bitümlü sıcak karışım uygulamalarına ait veriler derlenmiş ve uygulama temelinde 4680 adet gözlem içeren veri grubu oluşturulmuştur. Veri grubuna regresyon, temel bileşen, kümeleme ve diskriminant analizleri uygulanmıştır. Kümeleme analizi, veri grubunun 4 ana kümeye ayrılabileceğini göstermiştir. Belirlenen kümelere ve çeşitli kombinasyonlarına uygulanan standart aşamalı regresyon analizleri ile akma bağımlı değişkenini tahmin etmek üzere geliştirilen modellerde regresyon katsayısı % 73,9'a kadar ulaşmıştır. AbstractIn this study, flow value of the bituminous hot mixtures that can be determined by Marshall Test has been aimed to be predicted by regression models based on material and mixture properties. In this context, data on bituminous hot mix applications for the manufacturing of wearing and binder layers within the borders of Ankara Metropolitan Municipality have been compiled and a data group containing 4680 observations has been created on the application basis. Regression, principal component, clustering and discriminant analyses have been applied on the data group. The clustering analysis shows that the data group can be divided into 4 main clusters. With the stepwise regression analyses carried out on the determined clusters and their various combinations, the regression coefficient of models, which are developed to predict the flow variable, has reached to 73.9 %.
