ADHESION OF BITUMINOUS BINDERS WITH AGGREGATES IN THE CONTEXT OF SURFACE DRESSING TECHNOLOGY FOR ROAD PAVEMENTS TREATMENT

In this article the study is done for the adhesion of aggregates coming from various granite quarries of Ukraine with bituminous binder, namely with bitumen emulsion – for application in surface dressing technology for road pavements treatment. In the article there are used the Ukrainian and European testing methods for determination of adhesion in the “bitumen – aggregate” system. According to the Ukrainian method, there was determined the adhesion of residual binder with the chips surface after boiling in the distilled water and in the solution of glycerin and distilled water. As the European method, for the studies there was used Vialit Plate Shock Test. There were developed three bitumen emulsion formulations.

11. Borrowing and security

This chapter considers borrowing as an important method of financing a company’s activities, and security as a right of recourse against company property if the loan is not repaid on time. It begins by discussing security for financial obligations, paying particular attention to security contracts, the redemption or discharge of security and the realisation of security. It then turns to the registration of non-possessory security contracts, the priorities of legal and equitable charges and floating charges as a form of security and their crystallisation. The extent to which the assets of a company, to which anyone is considering extending credit, are already charged as security is also explained. The chapter considers three particularly significant court cases: Evans v Rival Granite Quarries Ltd [1910] 2 KB 979; Re Spectrum Plus Ltd [2005] UKHL 41, [2005] 2 AC 680; and Re Yorkshire Woolcombers Association Ltd [1903] 2 Ch 284.

The Imperial Granite Quarry of Domitianè-Kainé Latomia

The results of excavations carried out in 2002-2003 at the Imperial granite quarries of Domitianè-Kainé Latomia at Umm Balad, in the eastern Egyptian desert, are presented. The archaeological interventions affected both the extraction fronts and the associated enclave, made up of a fort and a settlement linked to the workers. These facilities, together with information from numerous documented ostraka, provide information on the organization and accounting of the quarry.

Investigation of Sheriff Stuart’s black granite quarries in Charlotte County, southwestern New Brunswick: implications for the source of the titanic headstones in Halifax, Nova Scotia

Robert Albert Stuart, the High Sheriff of Charlotte County, deserves credit for establishing the black granite monument industry in New Brunswick. In the late 19th to early 20th centuries, he opened three quarries in mafic plutonic rocks in the vicinity of the Chickahominy Mountain, north of St. Andrews: the Bocabec black granite quarry (1893), the Steen Lake black granite quarry (1895), and the Glenelg porphyry quarry (1906). Much of the information in brief articles in local newspapers lacks sufficient detail to gain a full understanding of the historical development of these quarries. To obtain a clearer timeline for production of stone from the quarries, the rock type in each was examined and compared to black granite monuments in nearby cemeteries known to be sourced from these specific quarries. Previous investigations did not entirely rule out the possibility that the Stuart quarries may have been a source for the headstones placed in the Fairview Lawn Cemetery in Halifax, Nova Scotia, to mark the graves of some of those who were lost when the Titanic sank in 1912. Our detailed analysis of rock textures and production histories leads us to conclude that none of the Stuart quarries could have been a source for the Titanic headstones and supports the previous assessment that they came from Charles Hanson quarry.
