The objective of this study was to investigate the thermal property of thermal insulation board produced from admixtures of pineapple leaf fiber and natural rubber latex at different proportion level and the thermal property was evaluated based on the American Society for Testing Materials standard. Thermal insulation boards were fabricated using a hot pressing technique at a temperature of 150 °C under a pressure of 100 kg/cm2 for 5 min to form a squared thermal insulation with the size of 35 cm and 0.9 cm thickness. The thermal conductivity of the thermal insulation was 0.057 W /m K with density of 338 kg/m3. The success of this study primarily proclaims a high feasibility of producing thermal insulation from pineapple leaf fiber and natural rubber latex as a substitute for synthetic fiber.

This paper discussed a research carried out to study the rutting performance of dense graded (AC) and Stone Mastic Asphalt (SMA) pavement using nanocomposite polymer modified binder. The study also focused on the determination of optimum proportion of additive to be used in the mixing process. Two types of asphalt binder with penetration grade, PEN 80/100 and performance grade PG 76 were added with nanopolyacrylate and natural rubber latex as asphalt modifier. The nanocomposite polymer modified binder was prepared by adding 6 percent of Nanopolyacrylate (NC) to the asphalt binder. Both SMA and AC asphaltic mixtures conformed to the Marshall volumetric properties criteria which indicate that these mixtures are durable. The Asphalt Pavement Analyzer ( APA) rutting test was performed to determine the rutting performance of AC and SMA asphaltic mixtures showed that the rut values for SMA14 mix varies from 0.8 mm to 1.9 mm and AC14 mix varies from 1.7 mm to 2.3 mm respectively. This indicates the beneficial use of Nanocomposite polymer as modifier especially on SMA14 mix.

: In Ghana, the main binder for asphalt roads is bitumen. However there are many cases of early road deterioration resulting sometimes from effects of temperature on asphalt binder (bitumen). For this reason several studies are on-going to develop bitumen suitable for the climatic condition in the country. This study examines some physical properties such as softening point temperature, viscosity, penetration temperature and specific gravity and chemical functionalities, peak intensity and new functional group of AC 10 grade bitumen modified with natural rubber latex (L) at levels between 1-5% and 10% as well as its effect on aging at 5 and 10% blends. Standard methods of determinations of the physical properties, Fourier Transform Infra-Red Spectroscopy (FT-IR) Test and Short term aging test were employed. Results indicated that upon addition of 1% natural rubber latex, all the properties tested decrease. Further increasing the percentage of natural rubber latex decreases penetration point but the softening point temperature, specific gravity and viscosity increases. Spectroscopy analysis result revealed that there was no change in peaks intensities of the blends as compared to the conventional bitumen. Aging test results indicated a change in mass of 0.112% for 5% blend and 0.152% for 10% blend. The study has shown that natural rubber could improve some properties of bitumen andcould be used for constructing more durable roads.

In India the leftovers of results of regular elastic latex are stored each year frequently wild causing disjoin natural and other financial negative effects. The ecological strong waste like elastic, swim tops, gloves and so on can be reused betterly so it is useful for what's to come. Numerous investigations have been done to discover other elective material to use as modifiers in bitumen blends on the improvement of its properties and expressway quality. Concentrates still today for the most part centered around mechanical and physical attributes of rubber treated blends in which swell elastic is utilized either as option in contrast to characteristic totals or as added substance. In this exploration Natural Rubber latex (as inflatable’s) has been utilized as bitumen modifier. Common elastic changed bitumen is utilized for the prolongation of life of state streets. The need to receive elastic for the utilization of development of the streets is predominantly that it lessens the expense of development and furthermore reused elastic is utilized as it limits the natural contamination. In this examination Natural Rubber latex (as inflatable’s) has been utilized as bitumen modifier. Bitumen when contrasted with the rubber treated bitumen is bit delicate when presented to traffic burden and temperature. The Rubberized bitumen shaped decreases perpetual distortions because of over-burden out and about and in this way unaffected by the progressions in environmental temperature and improves slide obstruction. Elastic expands protection from stream of bitumen at higher temperature and improves the protection from fragile break at low temperature. The upper surface layer of the asphalt has been made of rubber treated bituminous blends. Rheological attributes of rubber treated bitumen just as fundamental properties of the actualized, rubber treated bituminous blend are exhibited. The practices of the two modifiers were examined by far reaching research facility testing and assessment. It was seen that the expansion of normal elastic gave better by and large execution in the bituminous blends. Subsequently, this shows characteristic elastic may contribute toward better adaptable streets later on. The above properties increment the administration life of rubber treated streets much of the time to in excess of hundred percent when contrasted with that of bituminous streets. Accordingly changed elastic bitumen of streets will join reserve funds with security. Keywords: Inflatable Rubber, Remnants
