The effect on clays and the stabilizing effect of damp clays on ungraded natural aggregates germinated an idea upon which a mortar theory for bituminous mixes might be based. This mortar theory, stated briefly, is the formation of thin films of bituminous binder upon the minute particles of a mineral dust to form a bituminous mortar, and the mortar so prepared to be used to bond aggregates together into a bituminous mixture suitable for paving purposes. In order to test the validity of the mortar theory as quickly as possible, known methods of producing such thin films were studied and the impact process selected for this purpose in further tests.

Abstract: The main goal of an Individual Learning Package (ILP) is to assist teachers in creating learning environments that are more humanized. ILP's should permit students to learn at their own unique rates, to have alternative ways to meet stated goals, to plan their own learning sequences, and to be successful with varying levels of self-initiative and self-direction. Presenting the ILP approach to instructional management through curriculum design, the curriculum components are: what will be learned (concept, skill and value statements), what changes will occur (learning objectives), what will facilitate those changes (IL materials and activities), how evaluation can help (pre-,self- and post-evaluation), and finally, future goals. Organizing the ILP components and evaluating for ILP improvement are discussed.
