“…However, PET-modi ed paving blocks show increased compressive strength compared to unmodi ed Bitumen paving block samples. According to Udawattha 21 , the minimum strength requirement for 'class 4' for use of pedestrian walkways is 15N/mm 2 , therefore, the pavement block produced with 10% PETmodi ed bitumen with curing period of 28-days is suited for the construction of pedestrian pavement.…”

This study considers the utilization of bitumen modified with polyethylene terephthalate (PET) bottles waste as an alternative binder in paving blocks. The optimum bitumen content of asphalt concrete was modified with 2%, 4%, 6%, 8%, and 10% of PET waste. The compressive strength test, skid resistance, water absorption, and abrasion test were conducted on the paving block samples. Compressive strength test was conducted to verify the samples' compressive strength performance while water absorption and abrasion test were used to ascertain the durability properties of the samples. Results obtained for PET-modified bitumen concrete paving blocks (PMBCB) show an increase in compressive strength, skid resistance, and a decrease in the water absorption and abrasion loss when compared to unmodified bitumen samples. The maximum compressive strength for the PET-modified bitumen concrete was recorded at 10% PET replacement level. This implies that the utilization of PET-modified bitumen as binders in concrete paving blocks will not only help in waste recycling but also contribute significantly to the protection and preservation of the environment.

“…Beban dapat dikelompokan sebagai beban statik dan beban dinamik, dimana salah satu bentuk dari beban dinamik adalah beban kejut yang mana beberapa beban diterapkan dan dihilangkan secara tib-tiba (Udawattha et al, 2017). Beban kejut dihasilkan apabila dua benda bertumbukan atau apabila benda jatuh dan mengenai suatu struktur, uji beban kejut ini menggunakan alat impact testing machine (Dahlan et al, 2013).…”

Paving block merupakan salah satu elemen yang sering ditemukan dalam struktur bangunan, karena paving block mudah untuk dicetak dan dirawat. Paving Block yang dicampur dengan crumb rubber mempunyai berat yang ringan sehingga tidak terlalu membebani struktur pada konstruksi bangunan. Penelitian ini bertujuan untuk menguji kekuatan paving block di laboratorium yang dicampur crumb rubber dengan kandungan 0%, 5%, 10%, 15%, 20% dan 25% dari volume pasir. Ada 2 jenis paving block yang diuji yaitu berbentuk balok dan berbentuk heksagon. Hasil penelitian menunjukan bahwa tren yang sama seperti yang ditunjukan oleh penelitian sebelumnya. Semakin banyak kandungan crumb rubber pada paving block akan menurunkan kuat tekan paving block dari 20,34 Mpa pada kandungan 0% hingga 11,31 Mpa pada kandungan 25%. Di lain pihak, kuat kejut paving block akan meningkat seiring dengan penambahan crumb rubber dari 2 pukulan pada kandungan 0% hingga 21 Pukulan pada kandungan 25%. Dari kedua bentuk paving block, paving block bentuk balok memiliki performasi yang lebih baik. Paving Block bentuk balok yang dihasilkan dalam studi ini termaksud paving block mutu B sesuai dengan SNI 03-0691-1996 yang dapat digunakan untuk pelataran parkir.

“…Mud concrete block is a building material invented by the University of Moratuwa, Department of Civil Engineering. The concept is to use available soil and mix them with 6% of cement and used alternative to the brick and cement blocks, mostly available in the market [1][2][3][4][5]. The concept is to aggregate 'Concrete' made using earth/soil.…”

Cement is one of the key stabilizers for earth constructions since Roman civilization. The invention of cement was one step in the human civilization. However, cement has many issues especially when it comes to the environmental conservation. The production of cement creates a lot of carbon dioxide and destroys the natural setting to some extent due to the high consumption of clay and lime. Therefore, this study was conducted to alter the cement in mud concrete block. The study started with an inventory of alternative stabilizers that can be found in nature as well as in the human production. And then, the chemical patterns of those stabilizers were carefully identified to alter the typical Portland cement. Several mix proportions were tested and developed to alter the cement and found that the following materials can be developed to alter cement. A natural stabilizer such as tree resins, latex rubber stabilizer, waste ash, rice husk ash and many other ashes can be developed to chemically stabilize the earth blocks. However, out of the invented stabilizers, fly ash and rice husk ash have the high potential to replace cement.
