“…SSB, barajlar, kereste depoları, ağır nakliye yolları, yükleme rıhtımları, liman tesisleri ve otoparklar gibi çeşitli uygulamalarda uzun yıllardır kullanılmaktadır. Son zamanlarda, SSB karışımları, şehir sokakları, otoyollar ve şehirlerarası yollar olmak üzere karayolu uygulamalarında daha yaygın hale gelmiştir [3].…”

Silindirle sıkıştırılmış betonların (SSB), geleneksel betonlara kıyasla üretiminin hızlı olması, maliyetinin düşük olması ve daha iyi dayanıklılık performansı göstermesi nedeniyle günümüzde yaygın olarak tercih edilmektedir. SSB karışımları hava limanları, fabrikalar, petrol istasyonları, çeşitli endüstriyel zeminler ve özellikle barajlar, yollar gibi birçok alanda uygulanmaktadır. Bu çalışmada SSB uygulamalarının avantaj, dezavantaj, tarihçesi, mekanik ve durabilite özellikleri üzerine yapılan araştırmalar ayrıntılı olarak incelenmiştir. Mekanik özellikler kapsamında uçucu kül, yüksek fırın cürufu, çelik ve polipropilen lifler, geri kazanılmış malzemeleri içeren SSB karışımların basınç, eğilme dayanımı, çekme dayanımı, elastisite modülü, yorulma davranışı ve sünme performansı araştırılmıştır. Durabilite performansı olarak SSB karışımların yoğunluk özellikleri, geçirgenlik, boyutsal kararlılığı, donma-çözülme direnci ve termal özellikleri kapsamında literatürde yapılan çalışmalar incelenmiştir.

“…Traditionally, the critical cracking failure for a rigid pavement would be the cracks initiated at the bottom of the rigid layer due to repeated fatigue loading. However, field observations of cores and trench sections from in-service pavements have shown that premature failures may develop from the surface and propagate their way down, such as top-down cracking [26][27]. Recently, it was found that the crack could also initiate from the near-surface of rigid pavements.…”

In this study, six full-scale APT pavement sections, each 71.7 ft. long and 13 ft. wide, were constructed at the LTRC's Pavement Research Facility (PRF) using normal pavement construction procedures. The test sections include three RCC thicknesses (4 in., 6 in., and 8 in.) and two base designs: a 150 psi unconfined compressive strength (UCS) cement treated soil base with a thickness of 12 in. and a 300 psi UCS soil cement base with a thickness of 8.5 in. over a 10 in. cement treated subgrade. A heavy vehicle load simulation device (ATLaS30) was used for APT loading. In situ pavement testing, instrumentation, and crack-mapping were employed to monitor the loadinduced pavement responses and pavement cracking performance. The APT results generally indicated that a thin RCC pavement (thickness of 4 to 6 in.) would eventually have a structurally fatigue cracking failure under the repetitive traffic and environmental loading due to a combined effect of pavement cracking and pumping. The visible cracks first showed up on pavement surface as a single or several fine cracks along the longitudinal traffic direction within the wheel paths. The longitudinal cracks were then extended and gradually propagated to transverse and other directions under the continued loading, and finally merged into a fatigue cracking failure. Post-mortem trenching results showed that the majority of the cracks were bottom-up, but some did show developed as the top-down. The results further showed that all tested thin RCC pavement structures over an adequate base support would have superior load carrying capability. The 6-in. RCC sections carried an estimated 87.4 million and 19.4 million ESALs to failure for the soil cement and cement treated base, respectively. The 4-in. RCC section over the soil cement base performed well with an estimated 19.2 million ESALs to failure. The data also indicated that the more substantial base (i.e., soil cement) support generally provided additional structural capacity as compared the less substantial cement treated soil base. The APT results were then used to evaluate the pavement fatigue life, cracking pattern and failure mode of thin RCC-surfaced pavements, which led to the development of a set of RCC fatigue models for thin RCC fatigue damage analysis. Finally, a thickness design procedure that includes a fatigue model suitable for analyzing a thin RCC surfaced pavement structure was proposed and the corresponding construction cost savings when implementing thin RCC-surfaced pavement as a design option for a low volume pavement were estimated.

“…The compressive strengths, when removing the fly ash, were more than 5,000 pounds per square inch (psi) for both sections. The cost analysis showed that Arkansas may have saved upward of $1 million per mile through the use of RCC rather than traditional full-depth reclamation and an asphalt surface (7).…”

The Louisiana Department of Transportation and Development has seen a rapid decline of low-volume roadway serviceability in recent years as a result of oil and gas exploration within the Fayetteville Shale Play near Shreveport, Louisiana. Similar results are expected on the low-volume roadway network within the Tuscaloosa Shale Play, north of Baton Rouge, Louisiana, as exploration expands. The objectives of this research were to determine appropriate proportions of roller-compacted concrete mixture for the construction of accelerated loading test lanes and to document field construction activities. Concrete samples were produced with four cement contents to determine the effect of moisture and density; the samples were tested for compressive strength at 7 and 28 days of age. The field testing included nuclear density testing, thickness measurements, and field-prepared compressive strength specimens. A walking profiler was used to determine the international roughness index (IRI). All laboratory-produced mixtures exceeded a compressive strength of 4,000 pounds per square inch (psi). When the desired surface characteristics and density were considered, 450 lb/yd3 was chosen as the minimum cementitious content for the construction of the test lanes. The field construction results showed that the speed of construction affected the density, the IRI, and the surface characteristics. An increased speed of construction yielded a rougher surface texture (an increased IRI between 360 and 620 in./mi) and slightly lower densities. The compressive strengths were still adequate and exceeded 4,500 psi at 28 days old. On the basis of the field results, IRI values in the 100- to 130-in./mi range and compressive strengths exceeding 5,000 psi may be expected in a full-scale roadway construction effort.
